Description

[Detailed Description of the Invention] This application applies to cases where the floor surface is constructed by laying conduits, communication cables, electric wires, etc. on a floor plate finished with concrete, etc. so as to have a space necessary for piping and wiring. With regard to floorboards used in By stably supporting it on the floor plate via an adjuster, it is possible to create a floor surface that does not wobble.

Conventionally, a number of rectangular floor plates are laid on a floor plate finished with concrete, leaving spaces for piping and wiring, to construct a floor for a computer room, for example. A large number of adjusters are erected and fixed vertically and horizontally at intervals, each corner of four mutually adjacent floor plates is positioned on the upper support plate of the adjuster, and, for example, a projector is installed on the upper support plate. By locking the locking pieces into the locking holes provided on the lower surface of the corner of the floorboard, and supporting the four corner positions of a single floorboard with each adjuster in this way, a large number of floorboards can be laid. method, and a method in which a large number of floorboards are laid by installing adjusters vertically in advance on the lower surface of the four corners of a rectangular floorboard, and grounding the lower receiving plate of the adjuster on the floorboard. However, in both of the above methods, a rectangular floor plate is supported at its four corners, and the surface of the floor plate is usually rough, so under these circumstances, Adjusting the adjuster to maintain a horizontal plane using four-point support is extremely troublesome, and as a result, it takes a lot of effort and time to install the floorboards.Furthermore, the floorboards themselves have deteriorated over time. In the former case, the corner of the floor plate may separate from the upper support plate of the adjuster, damaging the horizontal plane. In addition, in the latter case, each time the adjuster rises from the floor and walks on the floor or the transport vehicle runs, the adjuster moves up and down in that position, causing inconveniences such as making unpleasant noises. Both of the above cases were not favorable in terms of the structure of the floor surface.

Therefore, the present application provides a floor plate for solving the above-mentioned inconveniences, and an embodiment thereof will be described in detail with reference to the drawings below. 1 is a rectangular substrate, and as in the past, it is made of aluminum die-cast or Made of hardwood such as particle board,
A facing board 2 made of a flexible material such as vinyl tiles or carpet is adhered to the surface thereof.
In the present application, the substrate 1 is divided into two parts diagonally to form two members 1a and 1b. The two divided members 1a and 1b have similar right-angled triangular shapes, and are preferably formed so that a part b of one of the two right-angled sides exists at one end of the hypotenuse a. The hypotenuse a is inclined inward toward the lower surface, and therefore, at the joint of the pair of members 1a and 1b, there is an inverted V-shaped gap p along the hypotenuse b, that is, the dividing line. The substrate 1 is bent in a mountain-fold shape within the range of this gap p. 3
1 to 34 are adjusters made by screwing together a fixed shaft 3a having a screw hole 4 at the center of the lower part and a screw shaft 3b having a rotatable ground plate 5 at the lower end. A plate 6 is integrally mounted horizontally, and the adjusters 31 and 32 are placed on the lower surfaces of the right angle corners of the members 1a and 1b through the mounting plate 6, respectively, so that the ground plate 5 does not protrude from the periphery of the member. In this state, it is fixed via a set screw 7 and is hung vertically. Further, a mounting plate 8, which is laterally longer than the mounting plate 6, is integrally and horizontally attached to the other adjusters 33 and 34, and the adjusters 33 and 34 are attached to the members 1a and 1b, respectively, through this mounting plate 8. At the lower surface positions of the other corners corresponding to the joints of the two, set screws 7 are installed so that the ground plate 5 does not protrude from the periphery of the member and the extensions 8' of the mounting plates 8 are in contact with the lower surface of the other member. It is fixed and vertically installed. As shown in FIG. 4, pins 9 are protruded from the extensions 8' of each of the mounting plates 8, and regulation holes are formed in the lower surface of the other member where the pins 9 come into contact with the extensions 8'. 10, and due to the loose fitting between the pin 9 and the regulating hole 10, the pair of members 1
The bending angles of the valley fold and mountain fold at the junction of a and 1b are regulated.

In this way, a flexible mounting plate 2 is adhered to the upper surface of a rectangular substrate 1 consisting of a pair of members 1a and 1b,
and an adjuster 31 on the lower surface of each opposing right-angled corner.
and 32, and are opposed to each other along a dividing line in the opposing line direction, and have adjusters 33 and 34 erected on the lower surface of each corner of each other, respectively, by adjusting the adjusters 31-34. As shown in Figure 1, it is laid on a floor plate B made of concrete or the like, and a conduit, communication cable, Electric wire D etc. are piped and wired.
The floor plate A configured in this manner has the following effects.

In other words, if the adjusters 31, 33, and 34 are now adjusted to a constant height, the rectangular floor plate A is supported at three points by these three adjusters 31, 33, and 34, and is supported at three points. Therefore, one plane is easily determined, and the position of the adjuster 32 is left in a free state. By the way, a pair of members 1a, 1
b are connected by a flexible facing plate 2,
Since the position of the adjuster 32, which is the fourth support point, is bendable at the joint part, that is, the position of the parting line, the position of the adjuster 32, which is the fourth support point, is always subjected to a downward force due to the weight of the member 1b, so that the adjuster 32 forms one plane. When it is lower than other adjusters 31, 33, and 34,
The members 1a, 1b are bent in a mountain-fold shape, and the adjuster 32 is connected to the other adjusters 31, 33, 34.
When the height is higher than , it bends in a valley-fold shape (see Figure 5). That is, the position of the adjuster 32 is allowed to move in the vertical direction, and the ground plate 5 of the adjuster is grounded on the floor plate B by the action of its own weight applied to that position. Therefore, the floor plate A as a whole has four pieces. It is supported on the floor board B by the adjusters 31 to 34 without any play. This effect is exactly the same even when one plane is formed by the adjusters 32, 33, 34 and the height of the adjuster 31 is different from the other adjusters 32, 33, 34.

Next, the adjusters 31, 32, and 34 are adjusted to a certain height to form one plane, and when the floor plate A is supported at three points by this, an extension of the mounting plate 8 is placed at the position of the adjuster 33. The weight of the members 1a and 1b acts through the portion 8', and the adjuster 33 receives this weight.
3 is lower than the other adjusters 31, 32, and 34, the members 1a and 1b are bent in a valley-fold shape in a state where the parts 1a and 1b are lower than the adjuster 34 side at the joint part, that is, the position of the parting line, and the adjuster When the adjuster 33 is higher than the other adjusters 31, 32, and 34, the members 1a and 1b are bent in a mountain-fold shape so as to be higher than the adjuster 34 side (see FIG. 6). That is, the position of the adjuster 33 is allowed to move in the vertical direction, and the ground plate 5 of the adjuster 33 is grounded on the floor plate B by the action of its own weight applied to that position. Therefore, the floor plate A as a whole has four adjusters. It is supported on the floor board B by 31 to 34 without any play. This effect is exactly the same when one plane is formed by the adjusters 31, 32, 33 and the height of the adjuster 34 is different from the other adjusters 31, 32, 33.

That is, according to the present application, the support of a rectangular floorboard is based on three-point support, which is the most stable way to form one plane, and the error in the height direction of the fourth support point is corrected by adjusting the error in the height direction of the fourth support point between the pair of members constituting the board. As a result, the floor board can be installed on the floor board B at its four corner positions without any looseness.

The above describes the case where the pins 9 provided on the extension 8' of the mounting plate 8 are loosely fitted into the regulation holes 10 provided on the members 1a and 1b, respectively, to regulate the bending angle of the pair of members 1a and 1b. However, instead of this, as shown in FIG. 7, a flexible piece 11 is arranged so as to straddle the joint between a pair of members 1a and 1b, and both ends of the flexible piece 11 are attached to members 1a and 1b, respectively. Also, the valley fold angle of the pair of members 1a, 1b can be regulated, and according to this configuration, the hypotenuses a of the pair of members 1a, 1b can be aligned vertically to each other without inclining the hypotenuses a. It is possible to arrange the members 1a and 1b to face each other with a required distance apart, and in this state to connect the pair of members 1a and 1b by the mounting plate 2, and also has the advantage of being easy to manufacture.

By the way, as mentioned above, a large number of floor plates A are laid on the floor plate B, and the communication cables and electric wires D routed in the space C formed between them are placed on the floor plate A from the required position as necessary. However, in this case, in order to prevent damage to the communication cable and wire D, the communication cable and wire D, which have been led out onto the floorboard A, are bent and placed horizontally along the floor surface. At this time, it is necessary to prevent damage to the bent portion, and FIG. 8 shows an example of a configuration for this purpose.

That is, notches 12 are formed at the intermediate positions of each of the four peripheral edges of the substrate 1 shown in FIG. A case in which the facing plate 2 is bonded 13' is shown.

Therefore, when the floorboards A are laid, the notches 11 face each other between the adjacent floorboards A, and the through holes 1 for leading out the communication cables D, etc.
4 is formed, and a communication cable D is connected from this through hole 14.
etc., on the floor surface, as shown in FIG. 9, a part of the mounting board 2 rises in a curved shape due to the formation of the non-adhesive part 13, and the flexibility of the mounting board 2 itself allows communication. Cable D, etc. will be held at its lead-out position, so even if cable D, etc. is bent in this state, excessive force will be applied to the bent portion, causing damage to communication cable D, etc. It is possible to resolve concerns such as giving.

FIG. 10 shows another embodiment corresponding to FIG. 8, in which the mounting plate 2 is bonded to the entire upper surface of the substrate 1, and the side edge is attached to the mounting plate 2 at the position of the notch 12. It is constructed by providing a cutting line 15 in orthogonal directions, and even when using this configuration, the cutting line 15
A part of the mounting plate 2 corresponding to the notch 12 rises up in a curved shape through the cutout portion 12, and due to the flexibility of the mounting plate 2 itself, the lead-out position of the communication cable D etc. is surrounded as shown in FIG. , effectively acts to protect the lead-out portion and prevent damage.

Figures 12 and 13 show that a large number of floor plates A are laid on a floor plate B to form a floor surface, and after wiring is installed in the space C formed between them, a fire occurs due to electrical leakage, etc. This example shows an example aimed at preventing the danger that may occur. Specifically, the lower surface of the substrate (only a part of the member 1a is shown in the figure) is made of a highly heat-soluble synthetic resin film. A covering piece or a bag body 16 is attached, and a liquid or powder fire extinguishing agent 17 is sealed between the board and the covering piece or inside the bag body 16. With this configuration, sparks at the time of shooting are sealed. Alternatively, in the early stages of a fire caused by electrical leakage, the covering piece or the bag body 16 is locally melted and damaged, and the extinguishing agent that falls from the melted and damaged part has the advantage of preventing the spread of the fire.

As for the shape of the substrate, of course, in addition to a square, a quadrilateral shape such as a rectangle or a rhombus can be applied.

Since the present application is constructed as described above, it is possible to easily adjust the adjuster and install the floorboard, and each corner of the floorboard is supported at four points on the floorboard without play. In addition, this state can be sufficiently maintained even if the board that makes up the floor board itself is deformed over time, the floor board can be easily kept in a horizontal state, and the cutout allows communication cables and electric wires to be easily maintained. can be easily led out onto the floor surface at a desired position, and the leading out part can be protected by a flexible facing plate, and the possibility of damage occurring at the leading out part can be effectively prevented, and fire extinguishing can be prevented. The presence of the cover or bag containing the agent has the advantage of preventing the spread of fire and providing high safety.
